Background: Our aim was to evaluate the effect of intravenous intralipid administration as an antidote on the poisoned patients' Glasgow Coma Scale (GCS), hemodynamic parameters, arterial blood gas analysis, and routine metabolic profile tests (i.e. urea, glucose, sodium, and potassium) in the setting of non-local anesthetic drug overdose. Methods: In this randomized controlled trial, a tota...

Although local anesthetics have an acceptable safety profile, significant morbidity and mortality have been associated with their use. Inadvertent intravascular injection of local anesthetics and/or the use of excessive doses have been the most frequent causes of local anesthetic systemic toxicity (LAST). Furthermore, excessive doses of local anesthetics injected locally into the tissues may le...

One of the main risks of local anesthesia is local toxic effects caused by accidental intravascula...

Cephalopod molluscs are among the most behaviorally and neurologically complex invertebrates. As they are now included in research animal welfare regulations in many countries, humane and effective anesthesia is required during invasive procedures. However, currently there is no evidence that agents believed to act as anesthetics produce effects beyond immobility. In this study we demonstrate, ...

BACKGROUND Pain and needle-phobia can be a problem during the application of local anesthesia with syringe and needle. OBJECTIVE To evaluate a jet-injection device (without needle) to deliver local anesthesia. METHODS Two hundred and six minor dermatological procedures using a jet-injection device for administering local anesthesia into skin tissue were performed. We comment on the technica...

One of the very real complications possible in the use of local anesthetic agents is a relative overdose of the drug, resulting in an inordinate and potentially dangerous serum level. Even when using strict and careful technique, problems can occur. The reactions cited in the aforementioned cases were most likely the result of the accidental intravenous injection of a local anesthetic agent. Tw...

Common practice during local anesthetic injection is to warn the patient using words such as: "You will feel a big bee sting; this is the worst part." Our hypothesis was that using gentler words for administration of the local anesthetic improves pain perception and patient comfort. One hundred forty healthy women at term gestation requesting neuraxial analgesia were randomized to either a "pla...
